Narrated by Ubaid bin Umair Once 'Umar (bin Al-Khattab) said to the companions of the Prophet "What do you think about this Verse: "Does any of you wish that he should have a garden?" They replied, "Allah knows best." 'Umar became angry and said, "Either say that you know or say that you do not know!" On that Ibn Abbas said, "O chief of the believers! I have something in my mind to say about it." Umar said, "O son of my brother! Say, and do not under estimate yourself." Ibn Abbas said, "This Verse has been set up as an example for deeds." Umar said, "What kind of deeds?" Ibn Abbas said, "For deeds." Umar said, "This is an example for a rich man who does goods out of obedience of Allah and then Allah sends him Satan whereupon he commits sins till all his good deeds are lost."
